UNITED STATES PATENT OFFICE.

BUTTER-WORKER.

Specification of Letters Patent No. 31,7 58, dated. March; 19, 1.861.

To all whom it may concern:

Be it known that I, P. G. WVooDARD, of Waterford, in the county of Erie and State of Pennsylvania, have invented a new and Improved Machine for forking Butter; and I do hereby declare that the following is a full and exact description thereof, referones being bad to the accompanying drawings, makmg part of this specification.

Figure 1, is a view of the machine in perspective Fig; 2, a plan of the same; Fig. 3, a view, in partial section, of a part detached, showing, on a larger scale, the details of its construction.

Like letters designate corresponding parts in all the figures.

The special objects of my invention are to produce a machine for working butter, perfectly efficient in action, yet of the utmost simplicity of construction, in respect to cheapness, the use of suitable material and that readily at hand, and with tools the most ordinary, and in hands, if necessary, but little skilled.

In regard to material, the machine, with two or three unimportant exceptions, is composed wholly of wood, which is in all respects well suited to the purpose. 7 How the machine is thus enabled to be constructed almost entirely of wood, with gearing movements, will be apparent from the description following. Almost any wood possessing no exceptionable qualities, may be used; and thus the material is near at hand in every locality.

A simple rectangular frame A, of the desired size and proportions, serves to mount all the working parts upon. The board, or table II, on which the butter is to be placed for working, is arranged in the frame substantially as shown, so that one, projecting end shall be lower than the other, in order that the butter-milk may quickly flow off and be caught in a receptacle placed for the purpose. This inclination is effected by having one of the cross-pieces of the frame, on which the butter board rests, somewhat higher than the other, or by shortening two of the legs of the frame A, as shown in the drawings. Channels, or gutters m, m, in the top of the butter board serve to conduct the buttermilk to the pro-per place for discharging.

The working of the butter is accomplished by means of a fluted roller E, passing over it by a reciprocating rolling movement, and

kept pressed down into it while moving forward and backward. The ridges '5, z', of the roller thus continually indenting channels in the butter and these in the direction of the inclination of the butter board, allow the butter-milk to flow out immediately, as fast as expressed from. the butter. The recipro eating traveling and rolling movement is given to the roller E, by causing its journals s, s,to roll ontwo horizontal supporting pieces 0, C, stretching across the sides of the machine and in order that it may 'keep firmly in place, andi not slip on the supporting pieces, its journals .9, s, are provided: with, radial pins f, f, projecting therefrom at regular distances around their peripheries, so as to enter corresponding rows of holes: 0, c, in the supporting pieces C, C, so that the pins ofeach journal thus serve as the cogs of a pinion, and the holes as the cogs of a rack. The pins are: made a little pointed and the holes somewhat flaring, so that they may work freely together; roller is turned forward and backward by means of a winch G, or its equivalent.

Since the fluted roller E, is made of wood, and is therefore comparatively light, and since it is required to press with considerable force upon the butter, it is necessary to hold it firmly down upon its rack supports C, C. I accomplish this by means of horizontal bars D, D, situated over the rack supports C, 0, parallel therewith, and at such a distance therefrom as to just allow the journals 8, s, of the roller to pass freely between.

In order to enable the roller E, to be readily removed for washing it, &c., the bars D, D, are respectively pivoted at one end, on posts cl, (Z, while the other end is held down by removable pins 9, g, on withdrawing which that end of the bars is left free to be raised away from the roller.

For the purpose of adapting the machine to different quantities of butter, it is necessary that the roller E, should be at different times, at different heights, above the butter board H. To accomplish this, I secure the rack pieces C, G, in head blocks B, B, B, B, one situated against each of the four corner posts of the frame A, substan tially as represented in the drawings. The bars D, D, are also located in notches h, 7, h, h, in the upper ends of said head blocks, and pivoted and secured therein as above set forth. These head blocks are made ad- The justable, up and down, against the posts of the frame A, by means of vertical slots 6, b, b, b, in said head blocks, and screws a, a, a, a, extending through them into the frame A, or by any other equivalent means. Thus, by loosening the screws a, a, a, a, the head blocks can be raised or lowered as much as desired; and then secured by again tightening the screws, thereby accomplishing the object desired, substantially as shown and indicated in Fig. 8.

The butter is turned and shifted upon the butter board as often and as much as desired. But it is very'desirable, if not absolutely necessary, to provide an automatic arrangement for shifting the relative position of the butter to the roller E, at every movement of the latter forward or backward. Otherwise, the ridges z, i, will continually travel in the same channels formed in the butter, and thus produce but very little eflect, unless the position of the butter is continually shifted by handa tedious and laborious operation. In order to efiect this automatic shifting of the butter beneath the flutes of the roller E, I give to the butter board H, a side play, or room for movement, equal, say, to one half of the distance between the adjacent flutes of the roller. Then two sides 20, 20, or their equivalents project upward from the butter board, so

that the roller will strike them alternately,

at the close of each forward and backward movement. The effect is, that the roller first moves the butter board one way, and then the other way, a distance equal to the extent of play allowed thereto; and thus to present the ridges 2', i, of the roller to the ridges of the butter beneath, at every successive movement of the roller, and make new indent-ations therein. This movement is indicated by dotted lines in Fig. 2. The means of accomplishing this is seen to be exceedingly simple, as well as effective.

hat I claim as my invention and desire to secure by Letters Patent, is

1. The combination and arrangement of the fluted roller E, and the butter board or table H, provided with sides or projections,

p, 29, so as to produce an automatic shifting of the roller upon the butter at every turn of its movement, substantially as and for the purpose herein specified.

2. The adjustable head blocks B, B, B, B, arranged and operating in connection with the other parts of the machine, so as to adjust the roller E, to any desired height above the butter board or table H, substantially as herein set forth. I
